There is no other way though. Climate change is not a technical problem, it's political. We've had the tech to fix climate change for long time, we know how to do it, that part is quite easy and obvious, we are just not doing it.
You can't say "other way" when you're comparing to something that isn't a way in the first place.
Climate change absolutely is a technical problem and not a political one. It's about the cause and effect patterns of actual weather phenomena, and has nothing to do with conflict resolution within human societies, or anthropocentric psychosocial rituals.
We don't really have the technology to purposefully engineer macro-scale climate patterns, and we absolutely do not have the technology to secure wide-scale cooperation among vast numbers of people with different value systems and incentive structures. We've never had that.
Science tells us how climate works, technology provides renewable energy, but it's up to politics to do the switch. If we don't, then we will simply run out of time, problem will grow, and then we will get into a dead end where we really won't have the technology to fix it. There was a last chance to do it right around these years, we blew it by two trump presidencies instead. If that isn't politics, then nothing is.
Where do you get the idea that politics has, or has ever had, the ability to do anything of the sort?
> There was a last chance to do it right around these years
You're not getting it. There was never any chance to do it. You might as well be arguing for sacrificing goats or reciting ritual incantations. There is no political solution to climate change, and there never was.
